OVEN FOR COLORING GLASS.

SPECIFICATION forming part of Letters Patent No. 580,248, dated April 6, 1897.

Application filed November 14:, 1896. Serial No. 612,117. (No model.)

To all whom, t may concern:

Be it known that I, JOSEF BIEMANN, of Jeannette, in the county of Westmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Ovens for Coloring Glass; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention has relation to ovens for coloring glass; and the object is to simplify the construction and to improve the efficiency of the same; and to these ends the novelty consists in the construction, combination, and arrangement of the same, as will be hereinafter more fully described, and particularly pointed out in the claims.

Figure lis a front elevation of myimproved oven for coloring glass. Fig. 2 is a vertical section through the line wx of Fig. l, and Fig. 3 is a similar view through the line y y of Fig. 2.

Like numerals and letters of reference indicate corresponding parts in the several views.

The structure is to be built of brick or other suitable material with the furnace A at the base, the said furnace having the door ce for the insertion of fuel, by means of which the oven is to be heated.

B represents the ash-pit, and has a door b for the removal of accumulation of ashes.

C O represent the smoke-fines, by means of which the smoke from the furnace is carried off through the chimney 8.

E represents the iris-basin, which contains the iris colors used in coloring the glass, and has the damper F,working in guideways e at the top of the said basin E, the said damper F being operated by the handle f, which is made vaccessible by the door G. The said damper is used for closing the channel h, leading into the iris-oven H, and also the rear flue I, which also leads into the iris-oven H. The smoke and heat from the said furnace A pass out through the holes m into the hollow section fn., then through the flue-holes 0, through passages p and q, then through the opening r into the section s, then through opening t into another section u, and through opening 'u and around through passage a: up through the chimney 8. The heat and smoke passing through the above-described tortuous passage thoroughly heats the iris-basin E and the iris-oven H, thus utilizing all the heat possible.

Two sliding gates O are provided at each end of the oven H and are very handy and convenient f or obtaining access to the said oven. The said doors O are of course kept closed during irisation.

Rails or tracks 3 are situated in the iris-oven H, as shown', and serve as a track and resting-place for the perforated plate 5, which is used for supporting the glass to be colored, the said perforated plate being inserted in position in the iris-oven H through one of the doors O, and may either lie flat upon the track 3 or be provided with rollers. In the present instance the rollers are dispensed with. A triangular damper W is situated and operated in the top of the oven H and can be lowered or hoisted, according to necessary requirement for large or small glassware.

The iris color used in coloring the glass is put in the iris-basin E, and when the damper F is open the gas therefrom passes up through into the iris-oven H, containing the glassware, by means of the channel h and the rear flue I. The said gas circulating through the perforations 6 of the said perforated plate colors the glass and passes out through the ue 7 into the chimney 8.

A peep-hole 9 opens into the oven H and is closed by the slide 10, the peep-hole being used to see Whether the glass is ready for irisation.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

l. The herein-described oven for coloring glass, consisting in combination of a receptacle forholding said glass, a chamber for holding said coloring-matter, means for heating said chamber and oven, a channel connecting said chamber with said oven, a second passage leading from said chamber to oven, a damper situated between said chamber and oven and adapted to regulate the gas from coloring-matter in its passage from chamber to oven, said gas passing from oven to chim- ICO ney, 8, means for heating said chamber and oven, substantiallyasset forth and described.

' 2. The herein-described oven for coloring glass, consisting of a chamber for holding` said coloring material, a receptacle for holding said glass, a channel for conducting gas from coloring material to iris-oven, an outlet for said gas, a furnace for heating coloring material and oven, means for carrying off smoke from furnace, said means consisting of a series of flues and tortuous passages Which ultimately lead to chimney2, atriangular-shaped damper situated in said oven,'sliding doors situated at each end of said oven, a peep-hole situated in one side of said oven for inspection of said oven, substantially as set forth and shown.

3. The herein-described oven used in process of `coloring glass, consisting, in combination, of a chamber for holding said coloringmatter, a chamber for holding glass, passages leading from said chamber to oven a damper for regulating said passages, lues for carrying off smoke from furnace, furnace for heating said oven and chamber, an ash-pit,'means provided for carrying off the gas generated from coloring material after being used,
